Android获取应用信息
书接上文: https://blog.csdn.net/qq_23025319/article/details/13473979
上篇文章介绍了,通过pacakeManager获取packageInfo,从而获取应用签名数据.
本文接着讲解packageinfo以及applicationinfo获取到应用的其他数据.
具体代码如下:
public class DetailsActivity extends Activity {
private static final String TAG = "DetailsActivity";
private String packageName;
private PackageManager packageManager;
private ImageView ivIcon;
private TextView tvLabel, tvPackage, tvVersionCode,
tvVersionName, tvSign, tvFirst, tvLast, tvPermission,
tvMin, tvTarget, tvDataDir, tvPath, tvSize,tv_other,
tvActivity,tvService,tvProviders;
public static void launcher(Context context, String packageName) {
Intent intent = new Intent(context, DetailsActivity.class);
intent.putExtra("packageName", packageName);
context.startActivity(intent);
}
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_details);
packageName = getIntent().getStringExtra("packageName");
if (TextUtils.isEmpty(packageName)) {
Toast.makeText(this, "包名为空", Toast.LENGTH_LONG).show();
finish();
}
packageManager = getPackageManager();
if (packageManager == null) {
Toast.makeText(this, "packageManager为空", Toast.LENGTH_LONG).show();
finish();
}
initView();
try {

}

other.append("processName:"+applicationInfo.processName+"\n");

tv_other.setText(other.toString());

}

if (permissions != null) {
StringBuilder strPermission = new StringBuilder();
for (String permission : permissions) {
strPermission.append(permission + "\n");
}
tvPermission.setText(strPermission.toString());
} else {
tvPermission.setText("未申请权限");
}
ActivityInfo[] activities = packageManager.getPackageInfo(packageName, PackageManager.GET_ACTIVITIES).activities;
if (activities != null) {
StringBuilder strAct = new StringBuilder();
for (ActivityInfo act : activities) {
strAct.append(act.name + "\n");
}
tvActivity.setText(strAct.toString());
} else {
tvActivity.setText("未获取到activities");
}
ProviderInfo[] providers = packageManager.getPackageInfo(packageName, PackageManager.GET_PROVIDERS).providers;
if (providers != null) {

strProvider.append(providerInfo.authority + "\n");
}
tvProviders.setText(strProvider.toString());
} else {

}

for (ServiceInfo act : services) {
strService.append(act.name + "\n");
}
tvService.setText(strService.toString());
} else {
tvService.setText("未获取到services");
}
} catch (Throwable e) {
e.printStackTrace();
}
}
