Application expected to run in background on interval crashes without LOGCAT after 500-1000 iterations
问题
我的应用程序预计由用户运行一次,后台进程将在应用程序运行时无限期运行。后台进程应该以5秒的间隔运行处理程序(我使用了 badoo 的 WeakHandler)。然而,在间隔的 500 到 1000 次迭代后,应用程序将在没有任何日志记录通知的情况下终止自身 (稍后我会提供截屏)。我将我的日志记录设置为 Verbose
和 No Filter
。
如何确保应用程序能够可靠运行,不崩溃?
build.gradle(:app)
apply plugin: 'com.android.application';
android {
compileSdkVersion 29
buildToolsVersion "29.0.2"
defaultConfig {
applicationId "com.example"
minSdkVersion 21
targetSdkVersion 29
versionCode 1
versionName "1.0"
testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
implementation 'com.badoo.mobile:android-weak-handler:1.0'
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'androidx.appcompat:appcompat:1.0.2'
implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'androidx.test.ext:junit:1.1.0'
androidTestImplementation 'androidx.test.espresso:espresso-core:3.1.1'
}
我的应用程序只有一个活动,即 MainActivity.java
。以下是我的 Runnable 示例:
private Runnable captureInterval = new Runnable() {
@RequiresApi(api = Build.VERSION_CODES.O)
@Override
public void run() {
android.os.Process.setThreadPriority(android.os.Process.THREAD_PRIORITY_BACKGROUND);
if (mMediaRecorder != null) {
File f = new File(videoPath);
try {
mMediaRecorder.stop();
} catch (RuntimeException e) {
f.delete();
e.printStackTrace();
} finally {
mMediaRecorder.release();
mMediaRecorder = null;
}
}
if (mVirtualDisplay != null) {
mVirtualDisplay.release();
mVirtualDisplay = null;
}
if (!mKeyguardManager.isKeyguardLocked()) {
initRecorder();
shareScreen();
}
mHandler.postDelayed(this, 5000);
}
};

My application is expected to be run once by the user and the background process will run indefinitely as the app runs. The background process is supposed to run a handler (I use badoo WeakHandler) on 5s interval.
However, after 500 - 1000 iterations of the interval, the application would terminate itself without any notification on the logcat (I will provide the screenshot later). I set my logcat to Verbose
and No Filter
.
How can I make sure that the application can run reliably without crashing?
build.gradle(:app)
apply plugin: 'com.android.application'
android {
compileSdkVersion 29
buildToolsVersion "29.0.2"
defaultConfig {
applicationId "com.example"
minSdkVersion 21
targetSdkVersion 29
versionCode 1
versionName "1.0"
testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
implementation 'com.badoo.mobile:android-weak-handler:1.0'

testImplementation 'junit:junit:4.12'
androidTestImplementation 'androidx.test.ext:junit:1.1.0'
androidTestImplementation 'androidx.test.espresso:espresso-core:3.1.1'
}
My application only has one activity, which is MainActivity.java
.
Here is my Runnable
private Runnable captureInterval = new Runnable() {
@RequiresApi(api = Build.VERSION_CODES.O)
@Override
public void run() {
android.os.Process.setThreadPriority(android.os.Process.THREAD_PRIORITY_BACKGROUND);
if (mMediaRecorder != null) {
File f = new File(videoPath);
try {
mMediaRecorder.stop();
} catch (RuntimeException e) {
f.delete();
e.printStackTrace();
} finally {
mMediaRecorder.release();
mMediaRecorder = null;
}
}
if (mVirtualDisplay != null) {
mVirtualDisplay.release();
mVirtualDisplay = null;
}
if (!mKeyguardManager.isKeyguardLocked()) {
initRecorder();
shareScreen();
}
mHandler.postDelayed(this, 5000);
}
};
